Shaw, also known as Twenty Three, is a private dam located in Weld County, Colorado, along the Lone Tree Creek. Built in 1908 for irrigation purposes, this earth dam stands at a height of 7 feet with a length of 950 feet. It has a storage capacity of 105 acre-feet and a normal storage of 53 acre-feet, covering a surface area of 26 acres. While the dam has a low hazard potential, it is rated as high risk due to its condition assessment not being rated and lacking updated emergency action plans.

Despite being last inspected in 1992, Shaw remains in a state of disrepair with no recent upgrades or modifications. The dam lacks a spillway and associated structures, raising concerns about its ability to handle a maximum discharge of 90 cubic feet per second. With the risk management measures, emergency contacts, and inundation maps not being updated, there is a pressing need for regulatory agencies like the Colorado Division of Water Resources to enforce stricter inspection and maintenance protocols to ensure the safety and integrity of Shaw for both water resource and climate enthusiasts in the area.
